Rear view system and adjusting method thereof

Abstract

A rear view system for a transportation device includes a rear view means, a sensor and a controller. The sensor is used for generating a movement signal according to the movement of the transportation device. The controller is used for controlling the rotation of the rear view means according to the movement signal. Moreover, a method for adjusting the visual angle of a rear view means equipped in a transportation device is also disclosed.

1 . A rear view system for a transportation device, comprising:
 at least one rear view means;   a sensor for generating a movement signal according to the movement of the transportation device, wherein the sensor is a differential or a gyroscope device; and   a controller for controlling the rotation of the rear view means according to the movement signal.   
   
   
       2 . The rear view system of  claim 1 , further comprising a transmitter electrically connected to the controller for transmitting the movement signal to a global positioning system. 
   
   
       3 . The rear view system of  claim 1 , wherein the rear view means is an exterior mirror. 
   
   
       4 . The rear view system of  claim 3 , wherein the exterior mirror has a driving means configured in the exterior mirror for rotating the exterior mirror. 
   
   
       5 . The rear view system of  claim 4 , further comprising a manual switch for controlling the driving means manually. 
   
   
       6 . The rear view system of  claim 5 , wherein the controller is electrically connected to the driving means and the manual switch for controlling the driving means. 
   
   
       7 . The rear view system of  claim 6 , further comprising a cell phone repeater electrically connected to the controller. 
   
   
       8 . The rear view system of  claim 6 , further comprising a digital video broadcasting antenna electrically connected to the controller. 
   
   
       9 . The rear view system of  claim 6 , further comprising a radio antenna electrically connected to the controller. 
   
   
       10 . The rear view system of  claim 1 , wherein the rear view means is an interior mirror. 
   
   
       11 . The rear view system of  claim 10 , further comprising a driving means coupled with the interior mirror for rotating the interior mirror. 
   
   
       12 . The rear view system of  claim 11 , wherein the controller is electrically connected to the driving means for controlling the driving means. 
   
   
       13 . A method for adjusting the visual angle of a rear view means equipped in a transportation device, comprising the steps of:
 sensing the movement of the transportation device; and   rotating the rear view means according to the movement of the transportation device.   
   
   
       14 . The method of  claim 13 , wherein the sensing step is performed by a differential. 
   
   
       15 . The method of  claim 13 , wherein the sensing step is performed by a gyroscope device. 
   
   
       16 . The method of  claim 13 , wherein the rotating step comprises:
 rotating the rear view means counterclockwise looking from the top of the transportation device when the transportation device makes a right turn.   
   
   
       17 . The method of  claim 13 , wherein the rotating step comprises:
 rotating the rear view means clockwise looking from the top of the transportation device when the transportation device makes a left turn.   
   
   
       18 . The method of  claim 13 , wherein the rotating step comprises:
 rotating the rear view means upwardly when the transportation device is climbing up.   
   
   
       19 . The method of  claim 13 , wherein the rotating step comprises:
 rotating the rear view means downwardly when the transportation device is climbing down.
